Looks like a first draft. Lots of little issues. Even just casually clicking around through a couple pages I see a bunch of stuff:
* It's a little odd that the home page scrolls vertically, but scrolling down simply gives me about 4 inches of empty space with a horizontal line in it.
* The "Education for the 21st century" text does not all fit on one line.
screenshot. Also...it appears that "education" is part of the image, while the rest is text. Not sure why you're mixing like that.
* If I scroll the home page slider all the way to the left, it does not end up flush with the blue area above it.

* There are duplicate mouseovers/alt tags and the texts don't always agree with each other:
screenshot * You appear to be using templates for the links without modifying them to reflect the page that is currently being viewed. For example, when I'm looking at the home page, there are two links to the homepage: one if I click on the PCS University button on the left, and another if I click on the PCS University header up top. If I go to the "Answers" page, the Answers button still takes me to the answers page. While this may be a valid way of doing it...it might be preferable if buttons corresponding to the currently viewed page were visibly highlighted to show that it is the active page, and for it to no longer be an active link.
* On the answers page you have a bunch of images that appear to be intended as filter/sort links for various categories. But these images don't actually do anything. In addition to them not doing anything I can also highlight them. This is both nonfunctional and tacky.
screenshot * There are places where sections headers don't line up with each other
screenshot * There are pages
like this one that have scrollbars that really shouldn't.
* Stuff
like this would look better if it lined up.
Not going to spend the next 5 hours documenting everything for you, but my impression is that stuff like this is going on all over the place. I don't mean to overstate things. Overall the site has a good appearance, if a bit simple. But there's a lot of carelessness evident.
